The parameters used for design and the existing conditions of the on-site area are incorporated to show how the final drainage design will accomplish the desired drainage objectives per the City of College Station Drainage Policy and Design Standards (DPDS.) GENERAL LOCATION AND DESCRIPTION: The 31.30 acre site is located in Edelweiss Estates, north of Rock Prairie Road. The property is bounded by Edelweiss Estates Phases 15, 12, and 13 to the east and by Edelweiss Business Center to the south. The property is bounded to the east by Wellborn Road, and is bounded to the north by Southwood Valley Section 24C. The site is mostly open with a few wooded areas. The site is gently rolling with an average slope of 2 .0% to 2.5%. · FLOOD HAZARD INFORMATION: This property is not in a 100-Year Flood Haz.ard Area according to the Flood Insurance Rate Maps for Brazos County, Texas and Incorporated Areas, effective July 2, 1992, prepared by the Federal Emergency Management Agency for the City of College Station (See Exhibit "A"). DRAINAGE REPORT EDELWEISS ESTATES , PHASES 14 and 16 PRIMARY DRAINAGE BASIN DESCRIPTION: The site naturally drains to the north. A ditch along Wellborn Road collects most of the drainage from the existing site and discharges into Bee Creek Tributary "A". DRAINAGE FACILITY DESIGN: Storm water from the site will be captured in the curbs and gutters and conveyed by RCP storm drain to the detention facility. The detention facility will be located in the north part of the site. Storm water from the detention facility will be discharged into the existing channel that will convey the storm water to Bee Creek Tributary "A". The point where the flow exits the proposed detention facility will serve as Study Point # 1 for this project. Exhibit "C-1" shows the rational calculations for the various drainage areas corresponding to the Drainage Area Maps (Exhibits B-1 and B-2). Exhibit "C-2" shows the inlet computations. Exhibit "C-3" shows the pipe size calculations for the storm drain. Note that a portion of Phase 14 (Salzburg Court) was studied with the development of Phase 15-B. Drainage from this street will be captured in storm drains that convey the storm water to the detention pond constructed with Phase 15-B. Exhibits C and D use drainage areas "Pond", "Bypass 1 ", and "Bypass 2" in calculations. Drainage Area "Pond" represents the drainage areas that are conveyed to and routed through the pond (2A, 2B, 3 , 5 , 6 , 7 , 8 , 9A, 9B, lOA, IOB , 11 , 12). Drainage area "Bypass 1" represents the drainage areas south of the pond that are not routed through the pond (IA, lB, 4). These areas are shown on Exhibit ''B-2". Exhibit "B-2" also shows that 0.72 acres of the existing conditions drainage area will be diverted to existing detention ponds constructed with phases 13 and 15. DRAINAGE REPORT 2 EDELWEISS ESTATES , PHASES 14 and 16 DRAINAGE DESIGN CRITERIA: All drainage is in accordance with the City DPDS. The design rainstorm is the 10 year event. Flow calculations for all drainage areas are based on the Rational Method. Manning's Roughness Coefficient "n" is 0.014 per the DPDS. The storage volume required for the detention pond is based on a triangular hydrograph routing of the flows (base= 3* Tc). The detention pond serves to detain all design storms. Exhibit "D-1" shows the routing and hydro graph plots for the 5, 10, 25, 50, and 100 year events at Study Point #1 . The discharge for the proposed detention :fu.cility will be metered to not exceed the existing runoff discharge from the site. The following summary table shows the Pre-development and Post-development flows at the study point. Study Point #1 (Outlet of Detention Facility) Design Event Pre-Development Post-Development Water Surface Elev. - Qs= 46 cfs /" 44 cfs ""\ 305.8 Qio= 53 cfs 49 cfs I 306.0 I Q25= 60 cfs 54 cfs 306.4 Qso= 69 cfs 60 cfs 306 .7 Qioo = 78 cfs 65 cfs 307.1 I Top of Benn= 308.10 DRAINAGE REPORT 3 EDELWEISS ESTATES, PHASES 14 and 16 The pond outfall device is a 24" diameter RCP. CONCLUSION: The Post-development flow is reduced below the Pre-development flow for the 10, 25, 50, and 100 year events. The 100 year event is contained in the pond and released through the pond outlet device. The drainage design for this site meets the requirements as stated in the City of College Station Drainage Policy and Design Standards.

Assistant City Engineer CITY OF COLLEGE STATION P.O. Box 9960 College Station, Texas 7784 2 RE: Edelweiss Estates, Phases 14 & 16 Dear Mr. Mayo: Attached please find two (2) copies of the revised Drainage Report. The marked items in the drainage report review for Edelweiss Phase 14 & 16 have been updated. The following items have been revised in order to be in compliance with the City of College Station 's Drainage Policy and Design Standards: I. Drainage Areas 4 , 8, 13 , and 14 from the initial report have been modified in order to more accurately simulate the post-development conditions. 2 . The area of the pond is now included in the post-development flow 3. The post-development peak flow is less than the pre-development peak flow In the initial report the post and pre-development areas did not match . This was a result of two areas being left out of the combined flow at the outfall of the pond. The area on which the pond will be constructed was not added into the final flow. The area of the pond is 0.74 acres and corresponds to drainage area 12 on the updated report. Also, the area along the ditch from Hannover Street to the pond was left out. This area equals 0.62 acres and has been added to the area labeled Bypass 1 in the Drainage Report . Drainage areas 4 , 13 , 14 from the initial report and the area along the ditch have been combined to create Bypass l. The existing area remained 24.51 acres and the new post-development area is 23 .78 acres. The remaining 0 .73 acres drains into Edelweiss Phase 15b & 12 . These areas are shown on Exhibit ''B-2". As shown in Exhibit D-1 , the post-development peak flows for the 5, 10 , 25 , 50, and 100 year recurrence interval storms are all less than the pre-development peak flows . Structure 8A is a Junction Box between inlets 8 and 9. Stormwater does not enter the Junction Box. There is not a drainage area associated with the Junction Box so it was not shown on the drainage area maps or exhibits. The times of concentration and flow velocities are calculated based on the chart titled "Average Velocities for Estimating Travel Time for Overland Flow". This chart is from TR-55 and provides a nomograph for overland flow and shallow gutter flow that we have converted into equations that can be used in the spreadsheet. This method may produce higher times of concentration but this is conservative compared to Table lll-2. Should you have any questions or need additional information, please advise.
